RESUMEN
BACKGROUND: Cervical rib is an important cause of nontraumatic thoracic outlet neurovascular compression. This study was undertaken as there is no known documented report on its prevalence in the study environment. AIMS: To evaluate the prevalence of cervical ribs and its variation with sex and age among patients presenting at radiological facilities for a chest radiograph. SETTINGS AND DESIGN: Retrospective evaluation of plain posterior-anterior view chest radiographs done in radiological facilities in Enugu, Southeast, Nigeria. SUBJECTS AND METHODS: Evaluated in this study were all 6571 chest radiographs consecutively obtained between 2009 and 2012 in three randomly selected radiological facilities in Enugu. STATISTICAL ANALYSIS USED: SPSS version 17 software was used in data analysis. Chi-square and student t-tests were used to test for the significance of findings at 95% confidence level. RESULTS: This study reports the overall prevalence of cervical ribs as 48 (0.7%) with a significantly higher rate in females 43 (1.1%) when compared to males 5 (0.2%) (P = 0.000). In 27 (0.4%) cases, the cervical ribs were bilateral; whereas in 21 (0.3%) cases, they were unilateral with 8 (0.1%) on the left and 13 (0.2%) on the right. There was no age-related variability with prevalence (P = -0.813). CONCLUSIONS: The prevalence of cervical rib in the study population is low and within the known range as seen in other geographical regions of Nigeria.

OBJECTIVE: Improvements in diagnostic testing and genital repair have significantly advanced the management of disorders of sex development (DSD). Challenges however, still exist in the management of DSD. This study evaluated the types, challenges of surgical management, and outcome of DSD in south-east Nigeria. METHODS: Retrospective analysis of 39 children with DSD managed from January 2005 to December 2013 at the University of Nigeria Teaching Hospital, Enugu, Nigeria. RESULTS: Types of DSD were: 46, XX DSD in 17 (43.6 %) cases; 46, XY DSD 16 (41 %); Ovotesticular DSD 5 (12.8 %); and one (2.6 %) 46, XY Ovotesticular DSD. Median age at definitive gender assignment was 3 years (range 2 months-14 years). Gender assignment was female for 20 (51.3 %; all 46, XX DSD, one each of 46, XY DSD, Ovotesticular DSD and 46, XY Ovotesticular DSD), and male for 19 (48.7 %; 15 of 46, XY DSD, 4 of Ovotesticular DSD). Eight cases reared as male before presentation required gender reassignment after evaluation and counselling. Genital repair was undertaken at mean age of 4.1 years (range 6 months-14 years). After average follow-up of 22.5 months (range 1 month-7 years), a total of eleven (28.2 %) developed procedure-related complications. Challenges were delayed diagnosis, inadequate diagnostic facilities, and need for gender reassignment. CONCLUSION: There is a wide spectrum of DSD in our setting. Time to diagnosis, evaluation, and outcome may be improved by public enlightenment initiative, focused education of healthcare personnel and provision of relevant diagnostic facilities through enhanced funding and collaboration.

BACKGROUND/OBJECTIVE: Ultrasonogrphy is a good modality for the detection of splenomegaly even when it is not clinically palpable. The objective of this study was to establish the normal values of splenic length in healthy school children in South-East, Nigeria and to correlate them with body indices. MATERIALS AND METHODS: This is a cross-sectional prospective study of 1315 children (633 boys and 682 girls) between the ages of 5 and 17 years. The splenic length was measured between the most superiomedial and the most inferiolateral margins, at the level of the hilum. Only the spleens that had normal shape and echotexture were measured. The mean splenic length and the 5 th and 95 th percentiles were determined for each age. The length was correlated with the sex, age, weight (WT), height, body mass index (BMI) and body surface area (BSA) of the subjects. A regression model for prediction of spleen dimension from age and body habitus was computed. RESULTS: There was a significant correlation between splenic length and age, P < 0.001. Males had statistically significant longer spleen length than females. The splenic length correlated best with BSA, followed by body WT and least with BMI. CONCLUSIONS: This study noted racial variation between the established Nigerian values and results from other countries of the world. For the first time, a baseline value for splenic size for the Nigerian Children of various ages has been established with a regression model for predicting the splenic sizes.

A case offibrodysplasia ossificans progressiva in a 3-year and 10-month-old Igala boy is presented. It was characterized by progressive ossification of connective tissue and muscles of the neck and chest. Characteristic digital anomalies particularly microdactyly of the hallux and pollex, hallux valgus, and clinodactyly were also noted. The 2nd to 5th metacarpals had epiphyses at both the proximal and distal ends instead of only at the proximal ends. Although the patient presented in the first year of life, the diagnosis was not made until in his fourth year of life. Early diagnosis of the disease is important in order to avoid all forms of trauma that may worsen the prognosis.
